Yet those crises turned the first week of Obama's vacation into a working holiday. He made on-camera statements on U.S. military action in Iraq and the clashes between police and protesters in Ferguson, Missouri. He called foreign leaders to discuss the tensions between Ukraine and Russia, as well as between Israel and Hamas.

"I think it's fair to say there are, of course, ongoing complicated situations in the world, and that's why you've seen the president stay engaged," White House spokesman Eric Schultz said.

Obama will return to the Vineyard on Tuesday and stay for the rest of the week, White House officials say.
